Integration of Google Billing Library into app

[thawsoe7@yahoo.co.uk]

Hi,
I was trying to create promo codes on the play console. It says to make sure that the app has been integrated with the Google Play Billing Library.

LiveCode Release RC nine dot six dot thirteen rc-1 states:
-The version of the Google Billing Library used on Android for in-app purchases has been updated to six dot two dot one

To be clear my app doesn't have any in-app purchases or any subscription purchases. I was simply wondering if the Billing Library was already included in the app package or whether I would have to follow the tutorial titled "How do I implement in-app purchases in LiveCode - Google Play Store?" to incorporate the library.

Thankyou

Please mark this as solved.
My app is a paid app (it does not include in app purchases or subscriptions). I created promo codes for it in the Play Console. A dialog pops up which says "Make sure you've integrated your app with the Google Play Billing Library". I clicked Create to create the codes. I downloaded the codes and tested one (which worked).
Thanks
